"""
Test script for ReveniumDriver (Universal Driver).

This script tests the universal Revenium driver that auto-detects providers
and creates the appropriate specific driver.

Prerequisites:
1. pip install revenium-griptape
2. pip install middleware packages for providers you want to test:
   - pip install revenium-middleware-openai
   - pip install revenium-middleware-anthropic
   - pip install revenium-middleware-ollama
   - pip install revenium-middleware-litellm
3. Set appropriate API keys for providers you want to test
4. Set REVENIUM_METERING_API_KEY in environment (optional for testing)

Environment Variables:
- OPENAI_API_KEY=your_openai_api_key_here
- ANTHROPIC_API_KEY=your_anthropic_api_key_here
- OLLAMA_HOST=http://localhost:11434 (default, optional)
- GEMINI_API_KEY=your_google_gemini_api_key_here
- COHERE_API_KEY=your_cohere_api_key_here
- REVENIUM_METERING_API_KEY=your_revenium_api_key_here (optional)
- REVENIUM_METERING_BASE_URL=https://api.revenium.io/meter (optional)

Note: This is the main driver that auto-detects providers and wraps the appropriate driver.
